Add parameter only to selected type of system family
Possibility add specified parameter to selected system family.
Why I must add parameter about plasterboard type, number plasterboard to all wall type example also to concrete wall? It's stupid.
Why? Then you have Concrete wall type where you have many parameters that do not make sense.
idea?
Possibility create a wall type option to assign an xml file with additional parameters. It will be possible to write values to the file through Revit.
